The adjustable aggregate screening device comprises a base, a rocker, a rectangular screen and a rectangular screen driver, the rocker comprises a sleeve, a sliding rod matched with the sleeve in an up-down sliding mode and a spring arranged on the sliding rod in a sleeving mode; the rectangular screen comprises a rectangular material frame, upper transverse strips fixed to the lower portion of the rectangular material frame at equal intervals, a lower screen located below the upper transverse strips and an adjuster used for adjusting the position of the lower screen in the longitudinal direction. According to the adjustable aggregate screening device, the longitudinal reciprocating swing function and the vertical vibration function are integrated, and the screening efficiency of needle-sheet-shaped aggregates can be improved. And the ratio of the vertical amplitude to the horizontal amplitude of the rectangular screen is designed to be 0.25-0.5, and compared with the amplitude ratio in other value ranges, th
